The apples known as “melimela,”3068 and the other sweet apples, relax the stomach and bowels, but are productive of heat and thirst,3069 though they do not act injuriously upon the nervous system. The orbiculata3070 arrest diarrhœa and vomiting, and act as a diuretic. Wild apples resemble the sour apples of spring, and act astringently upon the bowels: indeed, for this purpose they should always be used before they are ripe.
